The invention discloses a clutch transmission torque estimation method, equipment, a storage medium and a device. The method comprises the following steps: in a pure electric operation mode, according to a preset state observation model relational expression, a first motor torque and a first load end rotating speed, determining a target whole vehicle estimation resistance torque; in the sliding friction starting mode, according to a preset state observation model relational expression, the engine rotating speed, the second motor torque, the engine torque and the second load end rotating speed, the estimated transmission torque of a target clutch is determined; compared with an existing torque determination method, the method cannot be used for solving the problem of estimating the transmission torque of the clutch in the sliding friction starting process of the engine; in the engine starting process, the clutch torque is estimated through the second motor torque, the whole vehicle resistance torque estimated through the motor torque under the pure electric driving working condition, the engine rotating speed and the second load end rotating speed; the problem that the actual transmission torque of the clutch is difficult to determine in the sliding friction engine starting process of the hybrid power system can be effectively solved.
本发明公开了一种离合器传递扭矩估计方法、设备、存储介质及装置,本发明在纯电动运行模式下根据预设状态观测模型关系式、第一电机扭矩以及第一负载端转速确定目标整车估计阻力矩;在滑摩启动模式下根据预设状态观测模型关系式、发动机转速、第二电机扭矩、发动机扭矩、第二负载端转速确定目标离合器估计传递扭矩,本发明相较于现有的扭矩确定方法无法用于解决发动机滑摩启动过程中离合器传递扭矩的估计的问题,本发明在发动机启动过程中通过第二电机扭矩及在纯电动行驶工况利用电机扭矩估计的整车阻力矩和发动机转速及第二负载端转速共同来估计离合器扭矩,可以有效解决混合动力系统在滑摩启动发动机过程中离合器实际传递扭矩难以确定的问题。
